Geno YAY !
For the moveset, I think that ... Geno boost could maybe ... boost his "agility" and minus his defense
I know it's not really "SMRPG-ish", But I think it could be great in Brawl !
(Or random boost/minus, Atk + / Agi -, Def + / Atk -, Agi + / Def - ...)
(Oh, and will he have the "symbol" that he have when he is making a "Special move" in SMRPG ?)
But anyway, It look really promising ! (... Better than those two other Geno PSA's)
And, Long time ago I've done an Stock Icon for Geno, if it could be useful :
